Saggars

What is a saggar?

"One of the big essentials in a successful pottery business is a good saggar"

SAGGAR - Hand-built kiln furniture. Sometimes SAGGER or SHRAGGER. Used during firing. An open box, in different shapes and sizes, made of fireclay or saggar marl with added pre-fired grog and fired before use. Specifically manufactured to contain pottery during a biscuit, glost or sometimes decorating fire in a bottle oven.

The saggar protects the ware it contains from contamination by kiln combustion gases and ashes, and the action of the flames.

Saggars of a particular shape and size have particular descriptive names:

Ovals

Banjos

Hillers

Cheese saggars

Square saggars

Skimmer saggars

Cup saggars

Scorer saggars

Pigger saggars

Dottey saggars

Some say that the word saggar is derived from the word 'safeguard.'

In the "Description of The Country from thirty to forty miles around Manchester" by J AIKIN, MD published in June 1795, the word saggar is described as a corruption of the German word SCHRAGER, 'which signifies cases or suporters.'

SAGGAR MAKER

Occupation. Ovens department. Male. A highly respected and highly skilled occupation for a man in the ovens department of a potbank. One of the best paid jobs on a potbank. Other well paid jobs included dish makers and firemen. Watch the movie to see how it's done. Or rather, was done. The species is now extinct. The film shows the process of saggar making by the late Ralph Wheeldon, one of the last four saggar makers in the Potteries. Here he is working at the Gladstone Pottery Museum in Longton, Stoke-on-Trent, during the making of the film in 1981.

SAGGAR MAKERS BOTTOM KNOCKER

Occupation. Ovens department. Male. It was an occupation in the ovens department of the potbank. Usually a male - it was very heavy work. The saggar makers bottom knocker would work with the Saggar Maker as a team. A bottom knocker bashes and flattens a lump of saggar marl (or fireclay, as it is known sometimes) with a mawl (pronounced mow or mau) to make the bottom of a saggar. It takes about three minutes to knock a bottom. Saggar making is no longer an occupation in the pottery industry. The art and craft of the saggar makers bottom knocker has died out. Completely. In this movie you will see the saggar maker's bottom knocker - actually knocking!

SAGGAR MAKING DEMONSTRATION

Kevin Millward at Gladstone Pottery Museum April 2015

Movie by Valentine Clays
Saggar making with Kevin Millward at Gladstone Pottery Museum's 40th Birthday celebrations. Kevin learned the art of Saggar Making when he worked at Gladstone Pottery Museum . It's fair to say that Kevin really is the only man left who can do it, being taught by saggars makers themselves. Kevin used Valentine Clays ES 180 (Sculpting/Pizza Body) when making the saggars.

WHAT IS SAGGAR MARL?

Traditional saggar marl is a very particular type of clay. It is a coarse, grey coloured fireclay found along with coal measures in North Staffordshire. Mixed with grog to add strength. More grog was mixed into the clay used for the bottom clay of the saggar than the side clay, as the bottom needed to be stronger. The proportion of clay to grog varied.
